First Claim
Patent Images
1. A method for implanting at least one of (a) an object and (b) a substance into a patient, comprising:
- inserting a sheath into the patient, the at least one of (a) the object and (b) the substance at least partially disposed within at least one of (a) a proximal portion of the sheath and (b) a distal portion of the sheath; and
after the inserting step, pulling the proximal portion and the distal portion away from each other to expose the at least one of (a) the object and (b) the substance.

Abstract
A separable or splittable insertion sheath is for inserting a medical device into a patient. The insertion sheath includes releasably connectable ends or is configured to split into proximal and distal sections upon application of a predetermined level of pulling or twisting force to opposite ends of the insertion sheath. A medical device loaded into the insertion sheath is deployed by pulling the proximal and distal sections away from each other to expose the medical device.

22. A medical device system, comprising:
-
a) an implantable medical device; and
b) an insertion sheath sized for insertion of the medical device into a bodily vessel, the insertion sheath at least one of (a) including proximal and distal portions that are releasably connectable to each other and (b) configured to split into the proximal and distal portions at a predetermined location upon at least one of (a) pulling of the proximal and distal portions away from each other at a predetermined pulling force and (b) twisting the proximal and distal portions relative to each other at a predetermined twisting force, the medical device configured to be delivered into the bodily vessel one of (a) through and (b) in the insertion sheath and positionable within the sheath such that the at least one of (a) pulling of the proximal and distal portions away from each other and (b) twisting the proximal and distal portion relative to each other exposes the medical device. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
